Local rules & notes

Impermissible Occupancy Limitation: The city attempted to limit JADU occupancy to a maximum of two persons, which HCD identified as a violation of state law and potential fair housing discrimination. Restrictive Efficiency Kitchen Definition: The ordinance tried to limit JADU kitchens to appliances not requiring gas or service greater than 120 volts; state law allows any cooking facility with appliances. Exclusion of Proposed Dwellings: The city's ordinance incorrectly limited ADU development to parcels with 'existing' dwellings, whereas state law requires permitting ADUs on lots with 'proposed' dwellings.
